Elemental
A match-three game where every piece is a glowing energy cell rendered
entirely by a procedural GLSL fragment shader — no sprite art at all. The shader
is the sprite. Elemental is a showcase for Fyne's canvas.Shader
object type and the power of OpenGL inside a Fyne app.
The elements
Seven materials, each generated in GLSL and identified by its motion and palette rather than any label — you learn to read them:
- Plasma — swirling hot-pink energy
- Arc — electric cyan lightning
- Metal — rippling liquid chrome
- Lava — molten crust and glow
- Crystal — drifting, glimmering facets
- Nebula — deep violet star clouds
- Hologram — green scanlines and glitch
The dark background is itself a reactive shader: a slow nebula, a faint hex lattice, and a shock wave that radiates from every match.
How to play
- Tap a cell, then a neighbour to swap them — or drag between two cells.
- Line up 3 or more of the same element to clear them.
- Cascades, L / T / X crosses and 5-in-a-row lines trigger bigger explosions and bigger rewards.
Jeopardy: keep the core lit
A core-energy gauge drains continuously. Every match recharges it — more cells, deeper combo cascades and compound-match explosions all charge it harder. Let the core hit zero and it goes dark: game over.
Difficulty climbs with your score (level = score / 800), and each level speeds
up the drain — so the better you play, the harder the core is to keep alive.
Building and running
Requires Go and the Fyne prerequisites (a C compiler and OpenGL development headers).
go run .
To produce a packaged, distributable build:
go install fyne.io/tools/cmd/fyne@latest
fyne package

Overview ¶
Elemental is a match-three game where every piece is an "energy cell" rendered entirely by a procedural GLSL fragment shader - swirling plasma, electric arcs, liquid metal, lava, crystal, nebula and hologram. There is no sprite art: the shader is the sprite. It is built to show off Fyne's canvas.Shader object type and the power of OpenGL inside a Fyne app.
